To make good images I believe you have to be confident about your equipment, and feel comfortable using it. If not, then your energy is going to be going towards worrying about your equipment. You shouldn't have to thinking about that one little bit. If you know it works, and works well, then channel everything towards producing good work.

This is how I feel about the Tamron 14-150 lens. Do I trust it? Not sure yet. Does it work well? Not as well as it should is my feeling. Am I going to get rid of it? Well, not yet; I'll have to use it a little more. Maybe I'm missing something. Or, it could be it works differently from the Olympus and Panasonic lenses. It's definitely not as snappy as the Olympus 14-150. The Panasonic 14-140 II is also faster.

I'll be using this lens a little more on the GX8 but right now the best results comes from the GX7 with this lens.
